Description

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:12.0a2) Gecko/20120205 Firefox/12.0a2

Steps to reproduce:

Some schools use Magister (which uses Microsoft Silverlight) to correspond with their students. My school also uses Magister. Their site is https://amarantisnoord.swp.nl/ . This redirects to https://amarantisnoord.swp.nl/5.3.9/magister.aspx .

My OS is Windows 7 Ultimate x64 - SP1.


Actual results:

The site won't load, and says:

Er is een fout opgetreden bij het laden:

Expected results:

The site should load fine, and should ask for a username and a password. The site loads fine in Google Chrome Stable v16.0.912.77

It works if network.http.sendRefererHeader set to 0 or 1

When is this going to be merged in mozilla-aurora?

Comment 4

[Matthias Versen [:Matti]]

bug 410904 added just a http referer header to objects that the plugin requests. Every browser is doing that and Gecko had a bug and didn't send this referer. It looks like a bug in the site if adding the referer makes it work.

If this were true, wouldn't you expect Chrome to similarly not work?

Sending over to Fabien to take a look, since our suspicion is that this is in fact a regression. If we're able to pinpoint a site issue, we'll move this over to being a Tech Evangelism issue.

Please retest with tomorrows nightly.
We removed the referer on http post initiated by plugins
